First, prepare your glasses: Pour the salt and optional chili powder onto a very small plate. Run a small wedge of orange around the upper outer rim of your glasses (I prefer to only salt half of the rim). Roll the dampened rim into the salt mixture.

In a blender, combine the tequila, orange juice, lime juice, agave nectar or simple syrup, blueberries and ice cubes. Blend until smooth.Taste and add more a bit more agave nectar if the mixture tastes harsh or just doesn't quite sing, then blend again.

Pour the mixture into your prepared glasses. Carefully drop one big ice cube or a few smaller ice cubes into the drinks to keep them cold. Serve immediately!

Make more than one drink by adjusting the recipe accordingly... just don't fill your mixer over the "max" line!
